The Matlab library IRISFETCH allows seamless access to data stored within the IRIS-DMC as well as other data centers that implement FDSN web services. Routines are provided to access event (earthquake) information, station metadata, and time series data. All retrieved data is converted into structs for use in MATLAB scripts.

IRIS System for Portable Assessment of Quality (ISPAQ) is a command line application that calculates seismic data quality metrics locally, by leveraging MUSTANG R-code within a Python client. For LINUX and macOS.

Converts miniSEED to SAC format. An optional metadata file may be supplied that contains values for the SAC headers that are not available in miniSEED. This converter should work in Linux/Unix/MacOSX and Windows.
